D. After the system cancels the tool radius compensation, the imaginary tool nose point moves
to the positioning point, and when the tool is in the cycle inner, the tool diameter exceeds the
length of the rapid traverse of the first block, the overcut creates and No.255 alarms.

When G71
~
G73 is executed, the system temporarily cancels C tool compensation. When G70
is specified again, the system automatically recovers the compensation mode. Because the
system executes G71
~
G73, it does not execute the radius compensation, there must be the
finishing allowance in programming to avoid the overcut in roughing.
When G70 is cancelled, the radius compensation is cancelled firstly at the positioning point, a
radius compensation is created at the first block of the cycle body, and a compensation is
performed at the middle, and the radius compensation is cancelled in the course of returning to
the positioning point. When G70 cycle is executed, when the compensation mode is not
cancelled after the cycle ends, the system continuously executes the compensation in the
positioning point, which causes the undercut of the finishing cycle in the last block, so, In G70
cycle, the last block should exceed one tool radius value of the workpiece in programming.
